How to implement a web page that scales when the browser window is resized?

I can lay out the elements of the page using either a table or CSS float sections, but i

Thanks for all of the suggestions! It looks like the ugly stuff i had to do was necessary. The following works (on my machine, anyway) in IE and FireFox. I may make an article out of this for CodeProject.com later ;-)

This javascript goes in the section:

the starts off like this:

the DIVs float left for the layout. I had to set the height and width to percentages just shy of the full amount (e.g., 99.99%, 59.99%, 39.99%) to keep the floats from wrapping, probably due to the borders on the DIVs.

Finally, after the content section, another javascript block to manage the refreshing:

var isWorking = false;
var currentEntity = <%=currentEntityId %>;

//try to detect a bad back-button usage;
//if the current entity id does not match the querystring 
//parameter entityid=###
if (location.search != null && location.search.indexOf("&entityid=") > 0)
{
    var urlId = location.search.substring(
        location.search.indexOf("&entityid=")+10);
    if (urlId.indexOf("&") > 0)
    {
        urlId = urlId.substring(0,urlId.indexOf("&"));
    }
    if (currentEntity != urlId)
    {
        mustReload = true;
    }
}
//a friendly please wait... hidden div
var pleaseWaitDiv = document.getElementById("divPleaseWait");
//an example content div being refreshed via AJAX PRO
var contentDiv = document.getElementById("contentDiv");

//synchronous refresh of content
function RefreshAll()
{
    if (isWorking) { return; }  //no infinite recursion please!

    isWorking = true;
    pleaseWaitDiv.style.visibility = "visible";

    if (mustReload)
    {
        Reload();
    }
    else
    {
        contentDiv.innerHTML = NAMESPACE.REFRESH_METHOD(
            (currentEntity, contentDiv.offsetWidth, 
             contentDiv.offsetHeight).value;
    }

    pleaseWaitDiv.style.visibility = "hidden";
    isWorking = false;
    if (tmout != null)
    {
        clearTimeout(tmout);
    }
}

var tmout2 = null;
var refreshInterval = 60000;

//periodic synchronous refresh of all content
function Refreshing()
{
    RefreshAll();
    if (tmout2 != null)
    {
        clearTimeout(tmout2);
        tmout2 = setTimeout(Refreshing,refreshInterval);
    }
}

//start periodic refresh of content
tmout2 = setTimeout(Refreshing,refreshInterval);

//clean up
window.onunload = function() 
{
    isWorking = true;
    if (tmout != null)
    {
        clearTimeout(tmout);
        tmout = null;
    }
    if (tmout2 != null)
    {
        clearTimeout(tmout2);
        tmout2 = null;
    }

ugly, but it works - which i guess it what really matters ;-)
